Logsplitter Valve?

[49er]

Hi all,
I'm new but have been reading here for quite some time. I'm building a log splitter and have a question on the valves required. I want to control the main cylinder and the log lift. (and possibly the 4way wedge in the future) Can someone give specific part #'s or specs for the valves?

More info;
8 hp engine
16 gpm pump
16 gal tank
4" x 21" stroke main cylinder
3" x 12 lift cylinder

You will need one of these for the log splitting function, or if you want the double lever auto log splitting valve, like this.

Here is a two lever valve for the wedge, and lift

Install the joystick valve with PB, and then the log splitter valve.

If you don't like joystick valve, then a 2 lever valve like this.

You really don't need a lift cyl that big, unless you already have one.

If he uses more than 1 valve, will his first one have to have a PB outlet to run the second valve ?

Thanks for the quick reply.
Can I use a single valve for the lift and add another later for the wedge? Sorry if that is a dumb question, my background is in machining and sheet metal, still green and learning on hydraulics. Oh and the 3" cylinder had on hand and worked it into the design.

Will i need some kind of flow reducing valve for the smaller cylinder?

You can put smaller work port hoses on there if you want to reduce the flow rate, there are other flow restricted device you can add, but the valves themselves are spool type which would only require moving the handle a small amount vs fully to move the cylinder slower. You can make the hoses/lines to the up/down wedge out of 1/4" to reduce the speed it moves. i would put the dual spool valve on there right from the get go, and cap the 2nd spool if you intend on installing it ever. remove the handle on the capped spool till needed.

I haven't seen a log splitter valve with PB, so you would have to plumb in the two lever valve with PB first, and follow that with the log splitter valve. I don't see this happening, but if the valve with PB is being used, the fluid will be interrupted for the time you are using the valve. If the first valve is not using all the flow, then the remainder of the fluid will pass by to the next valve. You would normally be lifting or splitting, or setting the wedge. Only one function at a time.

An adjustable hyd needle valve could be used to set or control the cyl speed.
